Thanks for the reply.
I don’t recall a BIOS option to BOOT from USB.
That’s the first think you’ll need
How is this possible?
Create an boot file that contains io-usb and Fsys.umass, instead of
Fsys.eide (you’ll still need Fsys though).
I have several USB sticks with QNX 4.

Is it possible to boot with a USB stick?
Never tried it but in theory yes. I jsut wonder if there is enough room
in the image (640k limit) to put all the required software.

Fsys.eide works okay for us too. Rob is no doubt right that its
something to do with the size of the partition (we have only tested up
to 128M - 1G is a bit pricey still).
Fsys.atapi was less successfull for us. I guess different brands react
in different ways.
I recommend steering clear of Fsys.atapi as a non-boot filesystem, it
doesn’t work will with certain IDE emulation schemes by many new
Booting from USB (V1.0) seems to work just fine too with no obvious

We’ve used several different relatively small (32M, 64M & 128M) ide
flash drives (I don’t recall the brand off hand). All that is ever on
them is the .boot and .altboot files. We’re just using Fsys.eide with
no explicit options set.
How big is your flash drive? If it’s >= 1G, maybe you need to
partition it with a relatively small 120M or so root file system.
Also wierd things happen if your .boot file is too big. Here’s what
our build file looks like:
$ boot -v
$ Proc32 -l $(lnode) $(local) -p 1500 -t 300 -D
$ Fsys $(fsys_opts) -Hdisk$(fsys_gig)
$ $(fsys_driver) $(fsys_driver_opts)
$ mount -p/dev/hd0 /dev/hd0t77 /
$ sinit TERM=qnx

The FLASH drive is the (only) root file system and it is node 1. The

gibberish characters after the licence file error. Which driver did
you use? Any special parameters? What type of flash drive?
We are using EIDE hard drives but we wanted to replace them with
these FLASH drives for reliability reasons. Maybe it’s this brand
that doesn’t work although we tried it with DOS and it boots OK.
